Back in the dawn of the Internet, Yahoo! was the most popular
search engine. Submit url to bing or submit url to Yahoo!When Google arrived, its indisputably precise search
results made it the preferred search engine. However, Google is not
the only search engine and it is estimated that about 20-25% or
searches are conducted on Yahoo! Another major player on the market
is MSN, which means that SEO professionals cannot afford to optimize
only for Google but need to take into account the specifics of the
other two engines (Yahoo! and MSN) as well.

Optimizing for three search engines at the same time is not an
easy task. There were times, when the SEO community was inclined to
think that the algorithm of Yahoo! was on deliberately just the
opposite to the Google algorithm because pages that ranked high in
Google did not do so well in Yahoo! and vice versa. The attempt to
optimize a site to appeal to both search engines usually lead to
being kicked out of the top of both of them.

Although there is no doubt that the algorithms of the two search
engines are different, since both are constantly changing, none of
them is made publicly available by its authors and the details about
how each of the algorithms function are obtained by speculation based
on probe-trial tests for particular keywords, it is not possible to
say for certain what exactly is different. What is more, having in
mind the frequency with which algorithms are changed, it is not
possible to react to every slight change, even if algorithms' details
were known officially. But knowing some basic differences between the
two does help to get better ranking. A nice visual representation of
the differences in positioning between Yahoo! and Google gives the
Yahoo vs Google tool.

The Yahoo! Algorithm - Differences With Google

Like all search engines, Yahoo! too spiders the pages on the Web,
indexes them in its database and later performs various mathematical
operations to produce the pages with the search results. Yahoo! Slurp
(the Yahoo! spiderbot) is the the second most active spider crawler
on the Web. Yahoo! Slurp is not different from the other bots and if
your page misses important elements of the SEO mix that make it not
spiderable, then it hardly makes a difference which algorithm will be
used because you will never get to a top position. (You may want to
try the Search
Engine Spider Simulator and check what of your pages is
spiderable).
Yahoo! Slurp might be even more active than Googlebot because
occasionally there are more pages in the Yahoo! index than in Google.
Another alleged difference between Yahoo! and Google is the sandbox
(putting the sites “on hold” for some time till they
appear in search results). Google's sandbox is deeper, so if you have
made recent changes to your site, you might have to wait a month or
two (shorter for Yahoo! and longer for Google) till these changes are
reflected in the search results.

With new major changes in the Google algorithm under way (the
so-called “BigDaddy” Infrastructure expected to be fully
launched in March-April 2006) it's hard to tell if the same SEO
tactics will be hot on Google in two months' time. One of the
supposed changes is the decrease in weight of links. If this happens,
a major difference between Yahoo! and Google will be eliminated
because as of today Google places more importance on factors such as
backlinks, while Yahoo! sticks more to onpage factors, like keyword
density in the title, the URL, and the headings.

Of all the differences between Yahoo! and Google, the way keywords
in the title and in the URL are treated is the most important. If you
have the keyword in these two places, then you can expect a top 10
place in Yahoo!. But beware – a title and an URL cannot be
unlimited and technically you can place no more than 3 or 4 keywords
there. Also, it matters if the keyword in the title and in the URL is
in a basic form or if it is a derivative – e.g. when searching
for “cat”, URLs with “catwalk” will also be
displayed in Yahoo! but most likely in the second 100 results, while
URLs with “cat” only are quite near to the top.

Since Yahoo! is first a directory for submissions and then a
search engine (with Google it's just the opposite), a site, which has
the keyword in the category it is listed under, stands a better
chance to be in the beginning of the search results. With Google this
is not that important. For Yahoo! keywords in filenames also score
well, while for Google this is not a factor of exceptional
importance.

But the major difference is keyword density. The higher the
density, the higher the positioning with Yahoo! But beware –
some of the keyword-rich sites on Yahoo! can with no difficulty fall
into the keyword-stuffed category for Google, so if you attempt to
score well on Yahoo! (with keyword density above 7-8%), you risk to
be banned by Google!

Yahoo! WebRank

Following Google's example, Yahoo! introduced a Web toolbar that
collects anonymous statistics about which sites users browse, thus
way getting an aggregated value (from 0 to 10) of how popular a given
site is. The higher the value, the more popular a site is and the
more valuable the backlinks from it are.
Although WebRank and positioning in the search results are not
directly correlated, there is a dependency between them – sites
with high WebRank tend to position higher than comparable sites with
lower WebRank and the WebRanks of the top 20-30 results for a given
keyword are most often above 5.00 on average.
The practical value of WebRank as a measure of success is often
discussed in SEO communities and the general opinion is that this is
not the most relevant metrics. However, one of the benefits of
WebRank is that it alerts Yahoo! Slurp that a new page has appeared,
thus inviting it to spider it, if it is not already in the Yahoo!
Search index.

When Yahoo! toolbar was launched in 2004, it
had an icon that showed the WebRank of the page that is currently
open in the browser. Later this feature has been removed but still
there are tools on the Web that allow to check the WebRank of a
particular page.
